Extensive development of noncommutative geometry requires elaboration of the theory of differential Banach \*-algebras, that is, dense \*-subalgebras of C\*-algebras whose properties are analogous to the properties of algebras of differentiable functions. We consider a specific class of such algebra

The purpose of this paper is to study when a weight on an O U -algebra M M on a dense subspace D D in a Hilbert space H H is a trace weighted by a positive self-adjoint operator, that is, when there exists a positive self-adjoint operator β
